Specification` of Letters Patent.

Patented Jan., 27, 1,920..

Application filed February 18, '1919.` Serial No. 27.75843.,

T-all whom t may concern.'

Beit known that I, HARUO KAWASHIMAV, asubjectof the'Empe'ror of "J apan, resid'- ing at .North Platte, in the county of Lincoln andVState of Nebraska, have invented certainl new andY useful Improvements' in Track Lifters and Liners, ,of which the following is aspecification. i

T -hissinventionrelates to Vimprovements in jacks or lifting devices of thattype' especially designed for lifting and lining the rails A`of railway, tracks and the invention has for its primary objectto provide'a lifter affording av limited movement of theA track liftingbeam with relation tothe jack Sullicient'to permit of proper liningv of-therails.

Another object is to provideameans supplemental to theA` hingey rconnection between the jack and ybeamY to assist in elevating the 1atter-- Another object is` to providethelifting beam Awith laterally disposed rollers for convenience in transporting the lifterl over the rails of the track and sor arranged withrelation to the lifting ingersor `hooks ofy the beam `asto. be guided thereby.`

Withthese'and-othe'r objects iny view, as will appeary as the description proceeds, the invention comprises the,k novel arrangement of parts and combination of elements which will be more fully described inthe following specificationl and set forth with particu,- larity in the claims appendedhereto..

In the drawings;

Figure 1 represents a fragmentary transverse sectionalview of a railway track illus,- trating the lifter applied to use,

FigQQ represents a fragmentary plan view of the track and lifter, the latter being partially in 4 section,

Fig. 3 represents an enlarged'4 transverse sectional view through one terminaltof the lifting-beam illustrating one of the-supporting rollers in detail, andV i Fig. 4 represents an enlarged fragmentary perspective view of the hinge connection between the jack andbeam.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding partsv throughout, the several views, the numeral 5 indicatesa foot or base plate supporting the lower portion of a hollow post or casing 6 in which is slidaloly 'mounted the movable rack bar 7'hav1ng downwardly andY laterally directed ratchet teeth 8l formed along one edge. The opposed sidewalls of .the casing 6 are formed with longitudinal `slots 9 receivinglaterally projectingguide and lifting lugs 10 inte: grally connected `with the lower terminal of the bar 7 and designed tocoperate with the lifting beam to assist in nelevating the latter in a manner which will hereinafter appear. The sideV of the ycasingt contiguous to the toothed edge ,ofv the bar 7-is slOt'd andprovided with'lateral eXtensions'll receiving the terminal of a'socket lever 12' pivotally supported at13 between the extensions and' adapted to 4receive a detachable handle-14 for convenience inoperating the lever.

` A relatively yshort lifting pawl Mis -pivotally secured at 15 adjacent thepivoted t'erminal'ofthelever 12 andcoacts ywith" the teeth of the bar 7 to elevate the latter-during vertical oscillation., ofthe lever, the movement of said barbeing step-by-step, as will be'understood, during the oscillation of the lever. Duringthe period of inactiony of thepawl 14 incidenttotheup-stroke of the free ,end of the handle lljth'e bar is retained in adj usted position by the locking pawl 16 pivotally connected with the extension lllat apoint above the pin 13 and arranged'to coactrwith the teeth 8.y

A rail vengaging and lifting beam 171preferably substantially V-shaped to increase the inherent strength and rigidity of the beam is provided'terminally -along the longitudinal edge with rail ,receiving recesses 18 having the inner portionsvenlarged to define lifting fingers or hooks 19 which are V- designed for engagement beneath the. head of the rails 20 whereby the latter are lifted during elevation of the beam. The distance between the fingers 19 is such as to accommodate the rail heads and by a slightlongivtudinal'movementof'the beam the fingers or hooks 19 and the corresponding ends of the respective recessesvare engaged beneath the rail heads.

At the longitudinal center ofthe beam 17 a laterally proj ecting ear 21 is formed thereon and is received between the bifurcations of an integral lateral projection 22' carried adjacent the lowerl terminal of the bar 7 and a pin 223i is entered through registering apertures formed in the projections 21 and QZW-hereby'a pivotal connection between the ios the operative position of the jack is inclined and thus during operation the tendency of the lifter is to elevate and at the same time move the rails laterally. lf it is desired to move the track rails in a true vertical plane,

the jack is swung upon the pin Q3 in an arc of approximately 90 degrees which occupies a position at right angles to the beam 17 and thus when the latter is elevated the pull is exerted in a true vertical plane except for an inappreciable tendency to move the rails longitudinally.

The under edge of the beam 17 on opposite sides of the pin 23 is formed with inclined shoulders 24 adapted to be alternately engaged with the projections 10 of the rack bar-7 when the jack is swung in either direction against the beam. The abutment of the proiectionsV 10 with the shoulders 9A: materially relieves the pin 23 ofstrain incident to the lifting of the track although the lugs are ineffective to assist in elevating the beam when the jack is swung to the angu- .lar position above mentioned.

--As will be understood, the rails may be moved in either direction laterally, thedirection being controlled by the position of thev jack with relation to the beam. For instance, as illustrated in Fig. 1, the beam 17 during elevation moves toward the right moving the rails in a corresponding direction. However,`when the -jack is swung upon the pin -23 so as to engage the beam 17 at the right of the pin-the tendency during elevation of the beam is to move the rails toward the left.

One of the lateral surfaces ofthe beam 117-is'formed with cavities 25 communicating'with the recesses 1S and receiving stubshafts 26 supporting rollers 27 whichV pro- .ject slightly beyond thev surface of the beam and when thev latterv is tiltedl contact with vthe tread surfaces of the rails 20 and permit of convenient transportation of thel track lifter thereover.

1. In combination a jack including a movable bar, a track engaging and lifting beam, and a pivotal connection between the beam and bar extending in angular'relation to 'the direction of moi'fement 'of the latter whereby the position of 'the'bar with rela- -t-ion to the beam may be varied `to cause pressure to be applied to the' beam and eHect movement of the track engaged with the beam -laterallv iny either direction.

"2. lny combination, a jack including a llongitudinally movablev bar,fa track-engaging and lifting beam, and a pivotal connection between the bar and beam having its axis disposed in angular relation'to the direction 'of movement of the bar whereby the position of the bar with relation to the kbeam may be varied to cause pressure to be applied to the beam and effect movement of the track engaged with the beam laterally in either direction.

3. 1n combination a jack including a movable bar, a horizontally disposed rail engaging and lifting beam,-and 4a pivotal connection between the beam and bar permitting the jack to be swung into various angular positions with relation to the beam so as to move the latter upwardly and longitudinally in either direction according to the position of the jack.

1. ln combination a jack including a movable bar, a rail engaging and lifting beam, ,and a Ypivotal connection between the bar and beam having its axis disposed in angular relation to the direction of movement of the bar whereby the position of the jack with relationto the beam may be varied to ,produce a lateral movement of the track rails in either' direction without readjust- ,ment of the beam. Y

- `5. A tracklifter including a rail engaging and lifting beam, and laterally disposed Yrotatable rail engaging members carried by the beam for' transporting the lifter over .the rails and arranged to engage the rails Awhen the beam is turned to inoperative positiOn.V f

- 6. A rail lifter including a rail engaging and lifting beam, rail engaging fingers carried by the beam, and laterally disposed rotatable supporting members movable against the rails when the beam is tilted to an inoperative position for supporting and transporting the lifter.

Y 7. A track lifter including a track engaging beam, rotatable/track engaging velements carried by the beam movable .against the rails for supporting and moving the lifter 4thereon, and lifting lingers carried by the beam for engagement with the rails during the lifting operation thereof and constitut- .ing guides for the lifter during transportation. .f

8. A track lifter including a jack provided with a movable lifting bar, a track .engaging beam, a pivotal connectionrbetween the beam and bar, and means independentof the pivotal connection to transmit the movement of the beam. Y

9. A track lifter including a jack pro- `vided with a movable bar, a beam, a pivotal lconnection between the beam and thek bar, 'and bar carried means for engaging and assisting in lifting the beam. 10. A track lifter including a casing, a bar movableV longitudinally in said casing, means for elevating said-bar, apivotal conneotion between the beam and the bar, and means carried by said bar to engage and assist in lifting the beam.

l1. A track lifter including a casing, a bai' movably supported in said casing, means for elevating said bar, a track engaging and lifting beam pivotally connected with said bar, shoulders carried by said beam, and opposed shoulder engaging members carried by said bar movable into engagement with the shoulders during movement of the casing with relation to the beam to assist in elevating the latter.
